I get some of my ideas from watching my three daughters, but most of them come from my own memories of growing up. I can remember how romantic I was, not just about love, but romance in the classic sense - the romantic ideals: of honor and truth, of loyalty, sacrifice and fairness. Those were the elements that made a story satisfying to me.
When I first thought of the idea for 'Sweet Valley High, ' I loved the idea of high school as microcosm of the real world. And what I really liked was how it moved things on from 'Sleeping Beauty'-esque romance novels where the girl had to wait for the hero. This would be girl-driven, very different, I decided - and indeed it is.
